Drafted in the 20th round (621st overall) by the Philadelphia Phillies in 2010 (signed for $350,000)

While Kevin Gausman came into the year as the more highly touted prospect from Colorado, some scouts believe Walter will end up being the better of the two. He's a giant at 6-foot-6 and 220 pounds. Because of his size he sometimes has timing problems in his delivery, but he's a good athlete with clean mechanics for the most part. He hasn't shown the same velocity as Gausman, pitching at 88-90 mph with some sink and touching 92, but scouts believe it's in there. Walter has shown the ability to spin two different breaking balls, in a power curveball and a hard slider. They're distinctly different pitches and both show the potential to be above-average. He doesn't throw many changeups at this point, but that's not uncommon. Walter is committed to Boston College but may not get there, as he's getting fourth- to sixth-round buzz.
